I don't think any dealers will have a machine in that price range that you would like to be honest with you. What didn't you like about the Viking?
I agree with the others - check Craigslist but also check your local thrift stores - make sure you bring a needle, thread and a bit of fabric to try it out before you buy it
In my area, you can get a used sewing machine - even newer ones for less than $50, usually half that. If the weight is an issue, I'd suggest getting a wheeled case to take it to and from the car
